Hi keith
I get the same but would say its very little, and at about the same speed. i would say your right and is a tight spot somewere in the chain. i just rev a little bit more and if your at around change gear speed just slip the cluch a little. dont think its anything to worry about, but not being to technical minded give your dealer a ring and ask or if under warranty take it in. you may get some better advice from others here who know a lot more than me, sorry could not be of any more help. hope you get some better replys.
Safe riding herbz
